• Material - Steel: Steel is cheap, strong, and durable, making it a favorite for hinges of all types, despite it being slightly more prone to rusting than solid brass or stainless steel
• Mortise Hinge: Mortise door hinges mount flush with the surface of your door, providing maximum strength with the least interference with door functionality. It is recommended that three hinges be used on doors up to and including 7-1/2 feet, with one additional hinge for each additional 2-1/2 feet.
